This document summarizes several factors that can lead to interpersonal attraction according to social psychology research: physical appearance/beauty, personality, proximity, and similarity. Studies discussed found that people tend to see attractive, beautiful people as more desirable and competent. Additionally, having a warm, kind, or exciting personality is attractive to others. Proximity, or spending time near others, increases comfort levels and likelihood of attraction. Similarity in characteristics and interests between people also reduces conflicts. Reciprocated liking and gaining the approval of someone who was initially unimpressed can be especially rewarding.
